Abstract

이 발명은 유도자를 이용하여 용융 금속 탕출 장치 내의 용융 금속을 응고 또는 용융시키므로서 탕출 장치를 통한 용융 금속의 배출을 용이하게 조절하기 위한 것임. 용융 금속 용기의 탕출구에 설치된 유도자 작동 방법은 하나의 작업 상태에서는 유도자가 도전성 성형 부품과 전자적으로 유도결합된 상태에서 냉매 유체에 의하여 냉각되고 또 하나의 다른 작업상태에서는 유도자가 전자적으로 분리된 상태에서 냉매 유체에 의하여 냉각되도록 하는 방법으로 구성됨. 이 방법에 의하면 용융금속의 용융과 냉각을 위하여 유도자의 위치를 변경시킬 필요가 없음.The present invention is intended to easily control the discharge of molten metal through a molten metal extruder by using an inductor to solidify or melt the molten metal in the molten metal extruder. The inductor operating method installed at the tap outlet of the molten metal vessel is such that, in one working state, the inductor is cooled by the refrigerant fluid in an inductively coupled state with the electrically conductive molded part and the inductor is electronically separated So that the refrigerant is cooled by the refrigerant fluid. According to this method, it is not necessary to change the position of the inductor for melting and cooling the molten metal.
